Depression Diagnostic Aid Taste

ClinConnect Summary

The Taste-Mood Diagnostic Study is a clinical trial that aims to explore whether a taste test device can help diagnose depression. The study involves patients who have recently been diagnosed with Major Depressive Disorder (MDD) but have not yet received treatment. Participants will take taste tests before starting their first medication for depression and again six to eight weeks later. These taste test results will be compared with answers from mood questionnaires to see if there’s a connection between taste and mood improvement.

To be eligible for this study, participants should be between 18 and 75 years old, have a diagnosis of untreated MDD for at least three weeks, and not currently be on any antidepressant medication. They should also be in overall good health without serious other mental or physical illnesses. Participants can expect to complete a few visits for taste tests and questionnaires, and it’s important that they can attend all the required appointments. This study is currently recruiting participants, and those interested should consider discussing it with their healthcare provider.
